Spectroscopy: Tool for science and technology

Spectroscopy has provided not only the information but the inspiration for some of the most striking advances in the knowledge of the nature of matter and of the structure of the atom and the molecule. Very early the spectrum stimulated the minds and the imagination of men; and spectroscopic research is one of the keys which has unlocked the secrets of the universe.

From Newton's curiosity about the “phenomenon of colors” there grew spectroscopy, until recently the physicist's prime tool for exploring atomic structure, and now of ever growing usefulness to industry.
